UNITED STATES WALTER P; MURPHY, or NEW YORK, N. Y.

SHEET-METAL CAR DOOR.

Original application filed May s, 1920,

T (ZZZ w hom it may concern:

Be it known that I, lVAUrtrn P. MURPHY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Sheet Metal Car Doors, of which the following is a specification.

' My invention relatesto a sliding door for railway cars, 'more particularly to a door of this type for the side wall door opening of a box car; and the principal object of the invention is to provide a sheet metal door of novel and improved construction for use particularly in this situation which can be inexpensively manufactured and will be light in weight and at the same time strong and very rigid to withstand the hard usage to which box car side doors, because of their size, the way in which they are moved back and forth and their position on the outsideof the car structure are peculiarly liable.

A further object is to provide certain novel arrangements for weatherproofing the edgesof the door when closed.

The invention consists of the novel constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above stated object and such other incidental objects as will be referred to in the following description of the preferred embodiment of the invention illustrated in the accompanying drawing. In the drawing,

Fig. 1 is a fragmentary side elevation of the door and door frame.

Fig. 2 is a vertical sectional view on line 22 of Fig. 1, and I Fig. 3 is a fragmentary sectional plan on line 33 of Fig. l. T Referring to the drawing, designates the side sheathing of the car, 11 the side sill, 12 the side plate, 13 the forward door post, 14 the rear door post and 15 the flooring of the car, the door opening being indicated by the space designated 16 (Fig. 3). The door is arranged to slide back and forth across the door opening 16, the'term for ward door post meaning the post at the edge of the door opening overlapped by the.

front edge of thedoor when closed, the term rear door post meaning the'post at the other side of the door opening over I which the door slides in opening and closing. The door posts and flooring preferably Serial No. 379,807. Divided. and this application filed April 6,

project outwardly beyond the sheathing '10 as shown.

The door comprises a marginal, rectangular frame composed of members angular in cross section and a sheet metal panel secured to said frame and formed of one or more sheets of metal formed, preferably, with rigidifying corrugations. The marginal frame consists of an angle bar top member 17, the

horizontal flange 18 of which projects in wardly from the front plane of the door, a Z-bar bottom member 19 arranged with its intermediate web 20 in horizontal position, an angle bar 21 arranged with one flange 22 in the front plane of the door and projecting rearwardly, and the other flange 23 projecting inwardly, and an angle bar 24 at the rear edge of the door with one flange 25 in the front plane of the door and the other flange 26 projecting inwardly and formed with an oblique lip 27 inc-lined forwardly. The sheet metal panel is composed,

as shown, of three sheets of metal 28, 29 and 30 fastened together by rivets 31, the edges of said panel being secured flatwise to the depending flange 32 of the top member 17, the

outer upstanding flange 33 of Z-bar 19, andto flanges '22 and 25 of the forward and rear angle bars 21, 24. The sheets 28,29 and 30 are formed wit-h rigidifying corruga tions 34 which preferablytaper and termi of the sheets, these corrugations being preferably horizontally disposed and being because the lower part of the door is particularly liable to injury through shifting of the cargo. Moreover, the element 35 provides a smooth wear plate for bearing against the flooring 15 when the door is moved back and forth.

The door is provided with hangers 37 which preferably span the first of the corrugations 3st, as shown, these hangers being .85 nate at their extremities within the edges formed with upstanding lips 44 which overlap the depending flange 36 of Z-bar 19 this flange being preferably formed with offsets 44 so placed as to engage with the lips when the door is closed to force the ilnner edge of the door toward the flooring An angle bar stop strip 45 is secured to the forward door post 13. When the door is closed the angle bar at the front edge of the door bears flatwise against the outstanding flange 46 of the stop strip 45. This provides a reliable and strong stop for the front edge of the door. The construction moreover, effectually prevents rain, dust, cinders and the like from entering the .car at this point. i

Th rear door post 14 is recessed at 47 for the, side sheathing 10 and a weather strip 48 is arranged on the rear face of the outwardly projecting portion of the post. This strip consists of an angle bar having a flange 49 substantially flush with the front face of the post with its edge bent inwardly and forwardly to provide a lip 50 adapted,

when the door is closed, to be engaged by the lip 27 on the angle bar 24 at the rear ed of the door.

ealizing that the door construction above described might be changed in respect to certain details of construction without departure from my invention, I wish to be understood as claiming all modifications within the scope of the appended claims...
